Method for managing update in condition of multiple standby mode and broadcast receiving apparatus using the same

PURPOSE: An update method in multiple standby modes and a broadcast receiving device are provided to remarkably reduce energy consumed in the broadcasting receiving device by operating a standby mode. CONSTITUTION: When a user command is not inputted in an active standby mode, a processor determines an operation state of a background function in a STB(Set Top Box)(S240,S250). When setup time is over without executing the background function, the processor converts the operation mode of the STB into a passive standby mode(S260). When the user command is not inputted in the passive standby mode, the processor determines the update time(S270,S280). When the update time is arranged, the processor converts the operation mode into the active standby mode. [Reference numerals] (S210) On mode; (S220) Is an OFF button input, or is there no input of a command for a predetermined time ?; (S230) Active-standby mode; (S240,S270) Is a user command input ?; (S250) Set time elapsed without executing a back-ground function ?; (S260) Passive-standby mode; (S280) Is it reached to an update time ?; (S290) Is it reached to an update time confirmation cycle ?
